and rapid advance (only France)

Some control circuits do not receive voltage until the door and lock switch
S3 (2) are closed (point B ). Others receive voltage even when the door is
open (point A ). These feed points recur in other function diagrams.
The same conditions apply for feed points C and D . Point C does not
receive voltage until a switch S4 (10) in the safety lock delay unit is closed
(i.e. the door is locked). Point D receives voltage even when the door is
open.
Start
When a program is completed, the machine stops at program stage 53 and
the door can be opened.
The door must be closed for the machine to start. It is only when the door is
closed that the impulse generator B21 (5) in the coin meter receives
voltage. The coin lock B26 (5) also receives voltage since row 10a (3) is
closed at stage 53. This means that the lock infront of the coin slot can be
moved and a coin can be inserted.
When the correct amount of coins have been inserted into the coin meter
the impulse generator’s contact with
COM-NO position and the magnet for timer (9) receives voltage (row 34 (7)
is closed at stage 53).
At stage 54 row 34 is released but the timer advances to stage 1 since row
33 (8) is closed at stage 54. This design feeds the timer forward to stage 1
regardless of how long the impulse generator’s contact remains in COM-
NO position.

Rapid advance

By holding down S6 (6) during program operation, the timer can be rapid
advanced past different wash phases (rows 10b (3) and 34 (7) are both
closed at program stages 1 -46).
